背景图片可以延伸到div的边框之外吗？ [英] Can background image extend beyond div's borders?

问题描述

背景图片是否可以延伸到div的边框之外？是否overflow：visible适用于此？

解决方案

不，背景不能超出元素的边缘。 p>

overflow 样式控制元素在内容大于元素的指定大小时如何反应。

但是， div 中的浮动元素可以扩展到div之外，并且该元素可以有背景。但是，由于IE7和更早版本有一个错误导致 div 增长，而不是让浮动元素显示在其外部。

Can background image extend beyond div's borders? Does overflow: visible apply to this?

解决方案

No, a background can't go beyond the edge of an element.

The overflow style controls how the element reacts when the content is larger than the specified size of the element.

However, a floating element inside the div can extent outside the div, and that element could have a background. The usefulness of that is limited, though, as IE7 and earlier has a bug that causes the div to grow instead of letting the floating element show outside it.
